Child experiences swollen and painful gums and oral ulcers after fever

A child experiencing gum swelling, pain, and oral ulcers after a fever may be suffering from various possible causes, including but not limited to herpetic gingivostomatitis, streptococcal infection, or acute tonsillitis. These conditions can all lead to inflammation of the oral mucosa, resulting in symptoms such as oral ulcers and swollen, painful gums. Specifically, herpetic gingivostomatitis is caused by infection with the varicella-zoster virus, which invades the oral mucosa and gum tissues, leading to localized inflammation and ulceration. Streptococcal infections may damage the oral mucosa through stimulation by inflammatory factors. If left untreated, acute tonsillitis may also trigger the development of oral ulcers. To alleviate these symptoms, parents are advised to take the following steps: seek timely medical evaluation to determine the exact cause and receive appropriate treatment; maintain good oral hygiene, such as gentle tooth brushing and using fluoride-containing mouthwash; and, based on medical advice, administer medications such as antipyretics, analgesics, antibiotics, and vitamin B complex supplements as supportive therapy.
